Abstract
By analogy with thermodynamic notions, implying that the possibility for a reaction to proceed is determined by Gibbs' energy, which is equal to the difference of the energies for the final and initial products, it is proposed to calculate the difference of the sums of mean orbital electro-negativities for the final an initial products. A linear correlation has been established between Gibbs' energies of reactions and the mentioned differences, on the basis of vast experimental material for various reaction types. This correlation can be used to estimate the possibility of a reaction between the compounds for which thermodynamic data are unknown, in particular for complicated multi-component compounds.
